CVE-2024-53423: n/a in n/a
An issue in Open Network Foundation ONOS v2.7.0 allows attackers to cause a Denial of Service (DoS) via supplying crafted packets.
AI Analysis
Technical Summary
CVE-2024-53423 is a vulnerability identified in the Open Network Foundation's ONOS (Open Network Operating System) version 2.7.0. The vulnerability allows an unauthenticated remote attacker to cause a Denial of Service (DoS) condition by sending specially crafted packets to the affected system. ONOS is a network operating system designed to manage and control software-defined networks (SDNs), which are critical infrastructure components in modern telecommunications and enterprise networks. The vulnerability is categorized under CWE-400, which relates to uncontrolled resource consumption, indicating that the crafted packets likely trigger excessive resource usage or exhaustion, leading to service disruption. The CVSS v3.1 base score is 5.6 (medium severity), with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and low impact on confidentiality, integrity, and availability (C:L/I:L/A:L). This suggests that while the attack can be launched remotely without authentication or user interaction, it requires specific conditions or crafted packets that are not trivial to produce. The impact primarily affects availability by causing a denial of service, potentially disrupting network control functions managed by ONOS. No known exploits are currently reported in the wild, and no patches or vendor advisories are linked yet. Given ONOS's role in SDN environments, this vulnerability could affect network stability and reliability if exploited.
Potential Impact
For European organizations, especially those operating telecommunications infrastructure, data centers, or large enterprise networks utilizing SDN technologies like ONOS, this vulnerability poses a risk of network disruption. A successful DoS attack could lead to temporary loss of network control, impacting service availability and potentially causing cascading effects on dependent services and applications. Critical sectors such as telecommunications providers, cloud service operators, and large enterprises relying on SDN for network agility and management could experience degraded network performance or outages. This could affect business continuity, customer service, and regulatory compliance, particularly under stringent EU data protection and service availability regulations. However, the medium severity and high attack complexity reduce the likelihood of widespread exploitation, and the absence of known exploits suggests a window for proactive mitigation.
Mitigation Recommendations
European organizations should prioritize the following specific actions: 1) Identify and inventory all ONOS deployments, particularly version 2.7.0, within their network infrastructure. 2) Monitor network traffic for anomalous or malformed packets targeting ONOS controllers, employing deep packet inspection and anomaly detection tools tailored to SDN protocols. 3) Implement network segmentation and access controls to restrict exposure of ONOS controllers to untrusted networks, limiting the attack surface. 4) Engage with the Open Network Foundation and ONOS community to obtain updates, patches, or workarounds as they become available. 5) Conduct controlled testing in lab environments to understand the vulnerability's behavior and develop tailored detection signatures. 6) Prepare incident response plans specifically addressing potential DoS scenarios affecting SDN controllers. 7) Consider deploying rate limiting or filtering mechanisms at network ingress points to mitigate crafted packet floods. These measures go beyond generic advice by focusing on the unique aspects of ONOS and SDN environments.
